Try relevation then. Not to be confused with what happens when something is re-levied.

Although I would generally not recommend this for "re-rise", reascendance is particularly appropriate for nations. (Not sure why ascendance is so often used for nations, but it is.)

Thinking about how I would describe China as the former and future world leader, I would speak of the return or re-emergence of China as a world leader. I would be comfortable with someone else using reascendance but it would not be my first choice. Google says re-emergence is much more commonly used but I grant that reascendence is more precise.

I wouldn’t spell reemergence with neither a hyphen nor a diaeresis; re-emergence or the older reëmergence both look better than something that looks like a remerger of some sort.

@tchrist, I detest using diereses in English; I hesitate to use one even with naïve. It looks foreign and/or pretentious. I prefer re-emergence to reemergence but due to an issue with Google's Ngram viewer I mistakenly thought I was in a tiny minority. Re-checking, I see I'm not, so I edited my post accordingly.
